It was about America. I think the only overlap between "conservative" Republicans and religious fundamentalists is the "social conservatism", e.g., "family values", "law and order", etc. The quotes are because there's debate about what those terms really mean.

The key difference is that religious fundamentalists pledge their allegiance to the Church, not the country; not "God" either (although they might claim it to be so). They are tribal to their core and anybody outside their church is an "other" and is not worthy of being considered a fellow citizen.
